The purpose of this study was to investigate the possibility of using air potato (Dioscorea bulbifera) powder to make sponge cakes. The sponge cake batter was made by adding 0, 10, 20, 30, and 40% of air potato powder, and the resultant anti-oxidative properties and quality characteristics were analyzed. The study showed that the height, batter yield, and loss rate of sponge cakes decreased as increasing amounts of air potato powder were added, but the weight, viscosity, moisture content, and specific gravity increased. An evaluation of the color showed that the L and b values were highest in the control group but the a value was highest in the 40% group. There was no significant difference between samples in terms of cohesiveness, although the study showed a significant increase in the hardness, chewiness, and gumminess as the quantity of air potato powder in the sponge cakes increased. The total polyphenol content and DPPH radical scavenging activity increased noticeably as more air potato powder was added to the sponge cakes. The results thus showed that the study groups with the addition of air potato powder showed higher antioxidant activity than the control group.

Effect of baking on the physicochemical and sensory properties was investigated using a model system of sponge cakes incorporated with Ecklonia cava powder as a value-added food ingredient. Ecklonia cava powder was incorporated into cake batter at 5 levels (0%, 2%, 4%, 6%, and 8%, w/w) by replacing equivalent amount of wheat flour. After appropriate mixing, sponge cakes were baked at ${185^{\circ}C}$ for 20 min in an oven. The baked cakes were cooled to room temperature for 1 hr prior to all measurements. The specific gravity of batter increased gradually with increase in Ecklonia cava powder content. The specific volume of sponge cakes tended to decrease while baking loss increased. Volume of the cakes decreased with higher amount of Ecklonia cava powder in the formulation as indicated by the decrease in the volume index. Sponge cakes became darker and firmer with increase in Ecklonia cava powder content (p<0.05). Color, seaweeds smell, and taste were distinctively classified by the sensory analyses (p<0.05). Finally, correlation analysis indicated that level of Ecklonia cava powder incorporation was well-correlated with all the physicochemical and sensory properties studied except for $a^{*}$-value and sensory firmness (p<0.05, p<0.01 or p<0.001).

This study investigated the quality characteristics of butter sponge cakes added with whey protein concentrate (WPC)(0%, 10%, 30%, 50%, 100%) added as a fat substitute. The density of the dough of butter sponge cakes significantly increased with higher levels of added WPC and the pH decreased (F=248.38, p<.001). The moisture content also decreased significantly (F=3.151, p < .05). However, the volume (F=9.556, p<.01) and specific volume (F=11.15, p<.001) significantly increased. With respect to color, there was no significant difference in the lightness (L) value of the crumb, but the redness (a) value increased significantly with higher levels of added WPC (F=12.616, p < .001), while the yellowness (b) value decreased significantly (F=4.550, p<.01). Regarding the crust, the L values (F=3.791, p<.01) and b values (F=7.000, p<.001) decreased significantly with higher levels of added WPC, while the (a) values increased significantly (F=4.706, p<.01). The DPPH radical scavenging ability of the raw WPC used in the manufacture of butter sponge cakes was found to be 27.45%, but this increased significantly as the amount of WPC added to butter sponge cakes increased (F=45.237, p<.001). In a consumer preference test, the flavor, appearance, texture, odor, and overall acceptability were highest in the case of WPC-10 when taking advantage of the functional advantages of WPC as a lowfat substitute, confirming the development potential and optimal amount of WPC that should be added to butter sponge cakes.

The baking performance of yacon powder as a value-added food ingredient was investigated in a model system of sponge cakes. Yacon powder was incorporated into cake batter at 5 levels (0, 10, 20, and 30%, w/w) by replacing equivalent amount of wheat flour. The specific gravity of batter increased significantly while pH decreased significantly with the increase in yacon powder content (p < 0.05). The specific volume and moisture content of sponge cakes decreased while baking loss increased (p < 0.05). Volume of the cakes decreased with higher amount of yacon powder in the formulation as indicated by the decrease in the volume index. The symmetry index was not affected by the amount of yacon powder in the formulation (p > 0.05). Sponge cakes became darker and firmer with increase in yacon powder content (p < 0.05). Finally, the consumer acceptance test indicated that incorporation of yacon powder up to 20% in the formulation of sponge cakes did not significantly influence the consumers' overall acceptability.

To make sponge cake using Lentinus edodes powder, which is useful and valuable as a functional food material, we tested samples with 3, 6, 9, and 12% L. edodes powder to ascert200ain the quality characteristic and make optimize preparation. Samples and L. edodes powder-free control sponge cakes were compared in terms of quality characteristics including batter viscosity and specific gravity, moisture content, volume index, weight, color, textural characteristics, and sensory qualities, to determine the optimal ratio of L. edodes powder in the formulation. Viscosity and specific gravity of sample and control batter were not significantly different. Moisture content of the sample and control sponge cake also did not differ significantly, and weight of sample and control sponge cakes did not differ appreciably. The volume index of the samples displayed contrasting values, increasing with 3~6% L. edodes powder and decreasing with 9~12% powder. L, a, and b crust color values of samples sponge cakes were lower than those of control cakes. The L and a values of the control cakes was maximal, with values progressively decreasing with incorporation of more L. edodes powder. The b value decreased by 3% with the addition of up 6% L. edodes powder with no further decrease thereafter. L. edodes powder was the lower value. So was the color a, and L. edodes powder increased, a-values decreased. 3% difference was shown in b, the color and none between the samples with 6~12%. L. edodes powder showed lower values making a comparison with the control. Hardness and fracturablility were not appreciably affected by 3% L. edodes powder, but was affected by concentrations 6%. Fracturability og sample sponge cakes was consistently lower than control cakes. Fracturability made little difference in 3% samples, but it was not the same with more than 6% L. edodes powder samples; the samples showed lower value than the control. Adhesiveness was not significantly affected. Chewiness was lower in all sample cakes except those prepared with 3% L. edodes powder. Use of L. edodes powder conferreds higher resilience values as compared to thecontrols. Sensory attributes of color, flavor, softness and overall acceptability were the highest in control sponge cakes, as the amount of L. edodes powder increased, the acceptability decreased. L. edodes-flavor, pleasant taste and off-flavor were the lowest in control cakes, and values increased as the amount of L. edodes powder increased. The control sponge cakes showed the highest values in egg-flavor and moistness, which progressively increased as added L. edodes powder increased. The results indicate that control sponge cakes displayed were. the highest overall acceptability, with acceptability decreasing and it decreased as L. edodes powder content increased. However, 3~6% L. edodes powder can produce an acceptable product, and may be used as anoptimized mixture ratio.

This study was conducted to evaluate the quality characteristics of sponge cake consisting of 10%, 20%, 30%, 40% and 50% Helianthus tuberosus powder (HTP). With higher HTP contents in sponge cake, pH of sponge cake batter decreased significantly, whereas specific gravity was increased significantly (p<0.05). Meanwhile volume and symmetry indices of sponge cake were inversely proportional to HTP amounts. With higher HTP content in sponge cake, L value (brightness) of crumb significantly decreased (p<0.05), whereas a value (redness) significantly increased (p<0.05). b value (yellowness) of crumb in 40% and 50% HTP sponge cakes were significantly different from b value of crumb in 10%, 20% and 30% HTP sponge cakes. In 10~40% HTP sponge cake, L value, a value and b value all decreased significantly with higher HTP content in sponge cake. However in 40% and 50% HTP sponge cakes, there was no significant difference in any value. For texture characteristics, hardness of sponge cake significantly increased while cohesiveness decreased (p<0.05) with higher HTP content in sponge cake. On the other hand, springiness and gumminess of sponge cake did not change. Sponge cake containing 10% HTP showed the highest values for every organoleptic property. The results of this study suggest that sponge cake containing 10% HTP is the most appropriate for quality characteristics. This study also provides a way to increase the quality, texture characteristics, and organoleptic properties of sponge cake while reducing HTP content to less than 10% in order to qualify consumer taste.

The effects of differing baking ingredient formulations on physicochemical qualities and consumer preferences were investigated using sponge cakes incorporated with tomato powder, a healthy and beneficial food ingredient, as a model system. Tomato powder was incorporated into cake batter at four different amounts (0%, 10%, 20%, and 30%, w/w) by replacing equivalent amount of wheat flour. After appropriate mixing, sponge cakes were baked and cake quality attributes were evaluated after cooling. Specific volume decreased with an increase in the tomato powder substitution, although not significantly (p>0.05). On the other hand, baking loss increased from 10.3 (control) to 13.4 (30% sample) as the tomato powder level increased in the formulation. Lightness ($L^*$) decreased significantly from 79.5 to 74.1 whereas the firmness significantly increased with the higher incorporation of tomato powder (p<0.05). The consumer preferences on color, taste, and flavor, but not softness, were significantly affected by the amount of tomato powder incorporated in the sample (p<0.05). With respect to overall acceptability, the 20% sample received the highest mean score of 5.1, although this was not significantly different from the 10% sample or control (p>0.05). The incorporation of tomato powder, up to 20%, in the formulation of sponge cakes did not significantly influence the consumers' acceptability in all attributes tested.

The quality and characteristics of purple sweet potato sponge cake were studied with the addition of different proportions of purple sweet potato powder depending on storage period The pHs, heights, and weights of doughs were in the ranges of 6.3~6.5, 4.8~4.4 cm and 397~418 g, respectively. The sponge cake groups with the addition of different proportions of purple sweet potato powder showed significantly different characteristics in hardness, adhesiveness, cohesiveness, gumminess, and chewiness, according to texture profile analysis. The difference in colors of sponge cakes with addition with purple sweet potato revealed that L-value and b-value were significantly reduced but a-value especially increased according to the density. Using scanning electron microscopy (SEM), it was confirmed that the stoma size of purple sweet potato sponge cake become smaller and the stoma wall became thicker in proportion to the contents of purple sweet potato powder, which could result in an increased level of water content after a long period pf storage. According with the observations, water content remarkably increased after 4~6 days of storage and the ability to keep water content seemed to contribute to extention the shef-life of sponge cakes. In sensory evaluation, sponge cakes with high contents of purple sweet potato were preferred and cakes with the addition of 25% and 30% purple sweet potato powder was most preferred. It was expected that the shelf-life of purple sweet potato sponge cake was 4 days under the normal temperature.

The aim of this study was to evaluate the effects of oligosaccharides(fructo or isomalto ) contained in sponge cake on blood lipids and intestinal physiology in rats. The experimental diet was mixed with 30% sponge cakes. Normal male Sprague Dawley rats weighing about 530g were randomly assigned to three groups and placed experimental diets and deionized water at free access for 25 days. Rat in control group received a diet mixed with sponge cake containing sucrose only at 21.58g/100g diet and rats in the other two groups received diets mixed with sponge cakes of which 40% sucrose was replaced with each oligosaccharide. The results obtained were as follows: No significant differences in efficiency of food, liver weight and intestinal length were observed among groups. The cecal contents and cecal wall weights were increased more in fructooligosaccharide(FO) group than control. The pH of cecal contents decreased significantly in two oligosaccharide groups. The water contents of fresh feces in FO group were the highest and the those of two oligosaccharide groups were higher than that of control. Dry fecal weight increased significantly in isomaltooligosaccharide(IMO) group. Total serum cholesterol concentration was significantly lower in FO group. Serum triglyceride(TG) was not significantly different among three groups at p<0.05, but serum TG of FO group was lower than those of other groups. In conclusion, 40% replacement of sucrose with oligosaccharides in sponge cake may have beneficial effects on lipid metabolism and intestinal function in rats.

In this study, rice flour sponge cakes were prepared by replacing 50% of the sucrose with oligosaccharides. Isomaltooligosaccharide and fructooligosaccharide were used as the oligosaccharides. The effects of oligosaccharides on the physical, textural and sensory properties of the cakes were then examined. The oligosaccharides increased batter viscosity and decreased batter specific gravity and baking loss. The moisture content, specific loaf volume and loaf volume index of the cake increased by replacing 50% of the sucrose with oligosaccharides. Internal and exterior color determinations showed that the 'L' value of the sponge cake with oligosaccharides was lower than that of the control, indicating a darker crust and crumb with the oligosaccharide substitution. Decreases in textual hardness, chewiness, and brittleness occurred with the oligosaccharides. Sensory panels perceived that the oilgosaccharide darkened the crust of the rice flour sponge cake and the panelists rated the cakes with the oilgosaccharide substitutions as sweeter, softer and more moist. The rice flour sponge cakes with isomaltooligosaccharides had a significantly higher acceptability then the others.
